Figure 6:

Comparison of Power for common and rare diseases in epidemiological settings where the covariate is the self-reported number of cigarettes per day. Misclassified outcome* stands for high sensitivity and specificity (Sensitivity=0.84, specificity=0.96 for common diseases; sensitivity=0.857, specificity=0.997 for rare diseases). Misclassified outcome† stands for low sensitivity and specificity (Sensitivity=0.665, specificity=0.819 for common diseases; sensitivity=0.707, specificity=0.988 for rare diseases). Covariate* stands for small amount of covariate measurement error in number of cigarettes which was generated from NB(0.5,0.625). Covariate† stands for large amount of covariate measurement error which was generated from NB (3, 7.5).
